Free project PDK

Hi all

I want to share my project with members of the forum so they can make their PDK and prove

Hello, I built your circuit. When adjusting the 20k potentiometer, I hear a beep only at the very beginning and the very end of its rotation; holding it at that specific point makes the system somewhat sensitive. However, finding this exact spot is very difficult because the device sometimes detects a 1.5V spark from 30 cm away, other times from 80 cm, and sometimes from 2 meters away, triggering a beep. I am unsure if any components are faulty; I have replaced the transistors and potentiometers, yet the issue with the 20k potentiometer's balance persists. Also, I am using two antenna loops with a 4.7nF (4n7) capacitor, and the sensitivity is much better.

For loop L1, I used 147 turns of 0.30mm wire with an 8 cm diameter, and for L2, I used 100 turns with the same specifications; the antennas are arranged in a stacked figure-8 configuration.

My frineds, please help me for this

I made this scrap and all frequencies work from 60 to 800 kHz good at detecting treasures and the frequency is unimportant
The problem is how do we determine where the gold is buried?
Please Nikola Tesla I want a solution

Hello sharayar,i live iran,how a 1.5v spark test distance cm?

My Iranian brother, turn on the device and then activate a battery spark by connecting the negative to the positive for a very short moment and then disconnecting them, and the device will beep. From this, you can know the sensitivity of your device according to the distance at which it was affected, although this method has little to do with whether the device works or not, as these devices are just receivers of unknown signals, and we do not know how reliable they are in detecting treasures.
